[sr-dev] Why was IP type parsing removed from sdp in parser?

Hi All, Just curious as to why the parsing of IP type was removed from extract_mediaip in parser/sdp/sdp_helper_funcs.c. The latest code looks like below (could I suggest adding the highlighted part?): p.s. If there are no objections/responses I will commit to master branch. Cheers Jason int extract_mediaip(str *body, str *mediaip, int *pf, char *line) { char *cp, *cp1; int len; cp1 = NULL; for (cp = body->s; (len = body->s + body->len - cp) > 0;) { cp1 = (char*)ser_memmem(cp, line, len, 2); if (cp1 == NULL || cp1[-1] == '\n' || cp1[-1] == '\r') break; cp = cp1 + 2; } if (cp1 == NULL) return -1; mediaip->s = cp1 + 2; mediaip->len = eat_line(mediaip->s, body->s + body->len - mediaip->s) - mediaip->s; trim_len(mediaip->len, mediaip->s, *mediaip); if (mediaip->len == 0) { LM_ERR("no [%s] line in SDP\n",line); return -1; } /* search reverse for IP[4|6] in c=/o= line */ cp = (char*)ser_memrmem(mediaip->s, " IP", mediaip->len, 3); if (cp == NULL) { LM_ERR("no `IP[4|6]' in `%s' field\n",line); return -1; } switch (cp[3]) { case '4': *pf = AF_INET; break; case '6': *pf = AF_INET6; break; } /* safety checks: * - for lenght, at least 6: ' IP[4|6] x...' * - white space after */ if(cp + 6 > mediaip->s + mediaip->len && cp[4]!=' ') { LM_ERR("invalid content for `%s' line\n",line); return -1; } if(cp[3]!='4' && cp[3]!='6') { LM_ERR("invalid addrtype IPx for `%s' line\n",line); return -1; } cp += 5; /* next token is the IP address */ cp = eat_space_end(cp, mediaip->s + mediaip->len); len = eat_token_end(cp, mediaip->s + mediaip->len) - cp; mediaip->s = cp; mediaip->len = len; if (mediaip->len == 0) { LM_ERR("no `IP[4|6]' address in `%s' field\n",line); return -1; } LM_DBG("located IP address [%.*s] in `%s' field\n", mediaip->len, mediaip->s, line); return 1; }
